GRAIN-BINDING HARVESTER.

SFECIFICATION forming part of Letters Patent 1 l0.313,878, dated lviarch 17, 1885.

Application tiled July 10, 1883.

To all whom it may concern:

Be it known that I, J noon MILLER, of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Grain-Binding Harvesters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to an improvement in the packers of a grain-binding harvester, or to the oscillating arms whose office it is to compress the grain into a compact form preparatory to binding the same, and it is adapted to be applied to the packers of almost any binder, but more especially to binders in which the grain is to be moved up an inclined elevating and binding table arranged between the horizontal carrier of the grain-platform of the machine and the path of the driving-wheel.

It consists in adapting the packers to yield when subjected to undue pressure, whether resnlting from the compression of the grain or from the presence of obstructing material, by means of pendent swinging links supporting the heel or rear ends of said packers, said links being provided with swiveling supports, and having springs interposed between said supports for permitting the packers to yield.

In the accompanying drawings, Figure 1 is a perspective view of so much of a grain-binding harvester as is necessary to show my improvements; and Fig. 2 is atransverse section through the same, looking from the rear, showing the packers and needle-arm in elevation.

A represents one of the transverse sills of a grain-binding harvester, and A A the longitudinal frame-bars of the same, upon which and the transverse sills the binding and other mechanisms are mounted.

A A designate the frame-bars of the hinding-table, and which are supported by the longitudinal bars A A above referred to, being secured thereon by means of staplebolts a, passing through the bars A and around the bars A and A and held securely by nuts a upon the corresponding]y-threaded ends of the staple-bolts.

B represents the inclined binder-table, which is provided with suitable slots for permitting the movements of the packers and needle, hereinafter described.

0 0 represent the packers, which are of the (No model.)

1 form substantially as shown in the drawings,

and are mounted on cranks on the main bindergear shaft D. These cranks are designatedby D, and arranged in pairs, one of each pair being arranged upon the opposite side of shaft D to the other of the same pair, so that the operation will be that when one packer or series of packers is acting upon the grain for moving it upward and compressing it on the inclined bindertable the other will be withdrawn from the grain below the binding-table. The driving-shaft of the packers is mounted in suitable pendent bracket-s, D", on the transversely-inclined frame-bars of the binder-table, and when actuated carries with it in its revolution the crank-arms D, to the outer ends of which are pivoted, at or near their centers, the

oscillating packers O O, the construction thus far being similar to that of the Appleby binder. My packers differ very materially, however, from those in common use, in that they are adapted to yield, which end is accomplished by the following means: The heel end of each of the packers is provided with a forked portion, 0, between the divergent arms of which is pivoted a swiveling block, 0. Said block is perforated at c for the passage of the link hereinbefore mentioned, and designated by E, the block being adapted to slide freely upon the said link. The link itself is pivoted at its upper end to one of the transversely-inclined frame-bars of the binder-table, and between this pivotal point and the block 0 is interposed a coiled spring, 0, of the desired tension, surrounding the link, and serving when the grain presses against the packer to allow the latter to yield at its heel end, thus obviating any breakage of the parts, which might otherwise occur were the packers not adapted to yield to the pressure of the grain.

To prevent the block 0 from escaping from the link E, a pin, 6, is inserted through the lower extremity of the link, against which said block will abut when the packers are relieved of the pressure of the grain.

F represents the needle-arm, and is of a form substantially as shown in Fig. 1, being adapted to rock with the needle-shaft F, and having formed in connection with it a guard, F extending from the point of the needle, and formed substantially in the arc of a circle. The purpose of such guard, of which the needleshaft is the center when the needle-arm is ele- Vated and the binding mechanism is in operation, is to hold back the upflowing grain and separate it from that being operated upon by the binding mechanism until the bundle is completed and discharged, when the needlearm is adapted by suitable mechanism to resurne its position of rest below the bindertable, carrying with it the guard F and allowing the grain to again flow up within reach of the binding mechanism preparatory to the formation of another bundle.

The needle-shaft, or shaft upon which the needle-arm is mounted, has an intermittent motion imparted to it; but the shaft which actuates the packers has a continuous-revolution,

so that the packers are always at work, moving the grain up the inclined binder-table and compressing it into compact form for binding, the guard F on the needle, when the latter is up, serving to hold the grain behind the needle out of the reach of the packers, and serving, in connection with the latter and the needle, to effect a separation of the grain.

As before stated, the packers are driven from the main binder-gear shaft, but may be actuated from any suitable point, according to the desire of the manufacturer.

Having now described my invention, whatI claim as new is- 1. In a grain-binding harvester, the packers for moving the grain up to the binding mechanism, connected at or near the centers of their length with actuating-cranks, in combination with heel-supporting links, swiveling supports for the ends of said links, and springs interposed between said supports, whereby the packers are adapted to yield, substantially as and for the purpose described.

2. In a grain-binding harvester, packers arranged on revolving cranks, in combination with swinging links at the heel ends of said packers, upon which the latter are adapted to slide and yield by means of a coiled spring surrounding said link, substantially as and for the purpose specified.

3. In a grain-binding harvester, the packers O G, in combination with the blocks 0, links E, and springs 6, all for the purpose and substantially as described.

In testimony whereot'I have hereunto set my hand this 5th day of July, A. D. 1883.

JACOB MILLER.
